I dont know how i can make it more clear. Guess write down all combinations but thats very tedious.

Edit(I cant post anymore for 21 hours!?):
Its just weird, the crash was with 88% GPU usage. But that might be the case, but i have to play for longer to say if anything below really is stable. I did crash at the same settings yesterday tho with antialising on and today it was off.
Also i played LE since demo 3 years ago with the same GPU and i could run it on very high at least with 120 fps. Obviously not stable and some harsh drops in certain zones or certain monster types but thats just anyones issue for the most part.
